As I seem to be the only person posting on here who has actually had the SpaceOAR procedure, I guess an update is in order.
I now have just 4 radiotherapy sessions left (out of 37). As I mentioned previously, I had some discomfort at first after the SpaceOAR insertion, but that subsided after about four weeks and has not returned. Comparing notes with one fellow patient, same procedure by the same surgeon, same he experienced zero discomfort from the SpaceOAR. Radiographers and other staff at the centre where I am being treated have expressed surprise at my mention of the said discomfort, so I get the impression it isn’t usual. And don't get me wrong, it was only ever mild discomfort and certainly wouldn’t change my decision if I had to make it again.
If my mild level of side effects is anything to go by then it is doing a great job. But I don’t have another “me” to act as a control subject for comparison so it's impossible to know how things would have been without it.
I’ve now had 3 exercise sessions under the supervision of the physiotherapists and as someone who would never, ever, have set foot in a gym I’m really enjoying it. It’s all about building muscle. The only other people there are in the same or a similar boat so it’s all very positive and we can laugh with each other as we go through, or see each other go through, the same moments of discovering muscles we never knew we had.
